Movable guards

Movable guards are generally connected mechanically to the machine frame or to a fixed part close to the machine. The guard may be hinged or rail-mounted. They can be opened without using a tool and are only effective when they are closed.

Interlocking devices as safety solution

Movable guards may be associated with an interlocking device. When a safety gate is opened, for example, the interlocking device ensures that hazardous machine functions are stopped and an unexpected restart is reliably prevented.

Protection against unexpected start-up/restart of a machine

Once a safeguard has been triggered, a machine may not be restarted automatically after the protected field has been cleared. A restart is only possible via a reset on a control device outside the danger zone, with visual contact.

This is relevant, for example, when the energy supply is restored after an interruption or when a drive starts up unexpectedly due to a faulty control system.
